Abstract: An upper includes an upper main body that covers an instep of a foot. A first region and a second region adjacent to the first region are formed in the upper main body . The upper main body includes: a first linear body provided across the first region and the second region or provided only in the second region; and a second linear body provided in the first region while avoiding the second region and having an end located at a boundary portion between the first region and the second region. The first linear body and the second linear body have mutually different stretchability.

Abstract: A shock absorber includes a shock absorbing portion having a three-dimensional shape formed by a wall in which an outer shape is defined by a pair of parallel curved surfaces. The shock absorbing portion includes at least one three-dimensional structure body obtained by changing a shape of a unit structure body thickened based on a unit structure of a Schwartz P structure. The shape of the three-dimensional structure body in an unloaded state is a shape obtained by changing the shape of the unit structure so as to follow the shape change of the unit structure body, which is the regular hexahedron shaped space occupied by the unit structure body, into the trapezoidal space.

Abstract: A shoe sole which has a landing surface composed of three regions of a middle-sole region, a fore-sole region and a rear-sole region, and has a plurality of groove portions in the landing surface. The groove portions include: a first groove portion located in the fore-sole region, on a first imaginary line extending along the MP joint; a second groove portion located in the fore-sole region, on a second imaginary line extending along a line which connects a medial outer edge of the fore-sole region and a lateral outer edge of the middle-sole region with each other, in an area which is closer to a toe than to the first groove portion; and a third groove portion located in the rear-sole region, on a third imaginary line extending along a line which connects a medial outer edge of the rear-sole region and a lateral outer edge of the middle-sole region with each other.

Abstract: In a gas sensor where an exhaust gas is introduced into a chamber provided in a gas sensor element so that an oxygen concentration is reduced in a pump cell on the upstream side to detect NOx in the exhaust gas in a sensor cell on the downstream side, the surface of at least one of a solid electrolyte sheet and a shielding sheet that constitute wall surfaces of the chamber has a warped shape which is convex inwardly of the chamber at a position where the pump cell is formed. The warp amount is in the range from 0.10% or higher to 1.38% or lower, and the height in the stacking direction of the diffusion layer is lower than the average height Have in the stacking direction of the chamber at the position where the pump cell is formed.

Abstract: A shoe sole including: an outsole having a tread surface to be in contact with a road surface; and a midsole arranged on the outsole, wherein: the midsole is exposed in a central section of a rear foot section and an arch section; in the central section and a lateral side section of the rear foot section of the shoe sole, a diagonal groove is formed extending in a diagonal front-rear direction in the rear foot section to an outer edge of a lateral side of the rear foot section; an angle ?, formed between a virtual center line of the diagonal groove and a longitudinal axis connecting between a center of a heel and a middle point between a big-toe ball and a little-toe ball, is set in a range of 12° to 35°; and a virtual intersection point between the longitudinal axis and the center line is set within a range of 21% to 43% of a full length of the longitudinal axis of the shoe sole from a posterior end of the shoe sole, the diagonal groove extending to a point anterior and medial to the intersection point.

Abstract: A hexagonal cell honeycomb structure body has a plurality of hexagonal cells. Each hexagonal cell is surrounded by six cell walls in a hexagonal lattice shape. A R-shaped corner part of an approximate circular-arc shape is alternately formed at interior angle parts of the six cell walls forming each hexagonal cell. The three R-shaped corner parts are at the alternate internal corners of each hexagonal cell observed from a cross section of the axis direction of the hexagonal cell honeycomb structure body. A radius of curvature of each R-shaped corner part is larger than that of the interior corner part having no R-shaped corner part. The minimum radius of curvature of the R-shaped corner part is 2.8 to 5 times of a thickness of each hexagonal cell wall, namely within a range of 0.25 mm to 0.45 mm.

Abstract: A semiconductor pressure sensor having a cylindrical housing with an opening formed at its tip end which is exposed to a pressure atmosphere and a metal diaphragm for receiving pressure, which is formed in a wall of the cylindrical housing defining the opening. A metal oxide layer is formed in a surface of the metal diaphragm by oxidizing the surface of the metal diaphragm, and a glass layer is formed on the metal oxide layer. A semiconductor chip, on which a strain gauge is formed, is firmly and surely bonded to the metal diaphragm through the glass layer by virtue of the metal oxide layer. This semiconductor pressure sensor can measure high pressure with sufficient sensitivity and high accuracy.
